Metallic carbides, especially those of Group IVB, VB and VIB, all have a melting point above 3273K, of which hafnium carbide and tantalum carbide are 4160K and 4150K, respectively, and are the highest melting point among the currently known ones.Most carbides Their hardness is greater than 1800kg · mm2 (microhardness is one of the methods for the hardness, which is mainly used for cemented carbide and hard compound, the microhardness 1800kg · mm2 is equivalent to a Mohs-diamond hardness of 9 )
